    摘要: A method for making a composite extrusion die for making a cellular honeycomb structure with thin cell walls. The method includes the steps of drilling a grid of separate feed holes/channels into an inlet face of an extrusion die base element, and cutting a grid of intersecting primary outlet slots into an outlet face of the base element, where every alternate one of the primary outlet slots is in direct communication with a plurality of the feed channels. Further, the method includes cutting a grid of intersecting secondary outlet slots into the outlet face, where each one of the secondary outlet slots bisects each one of the primary outlet slots. The method further includes scoring a plurality of indentations into that region of the outlet face that does not contain any of the primary and secondary outlet slots, and filling each of the feed channels and each of the primary and secondary outlet slots with a filler material. Further, the method includes placing a bonding material onto the outlet face and into each of the plurality of indentations, and permanently attaching to the outlet face, a first side of a capping plate having a plate thickness not greater than 0.060 inches. Finally, the method includes cutting through the capping plate a grid of cap slots having a slot width not greater than 0.007 inches. The method further comprises eliminating the filler material from each of the feed channels and each of the primary and secondary outlet slots.

    摘要: An extrusion die for forming a cellular honeycomb structure having a finned protrusion extending from at least one cell wall of the honeycomb structure. The extrusion die is a composite extrusion die that comprises a primary extrusion die body having an inlet face and an outlet face, and at least a first insert member that is secured into a first intersection formed by a pair of intersecting slots at the outlet face of the primary extrusion die body. More preferably, a plurality of insert members are secured into a plurality of intersections, each intersection being formed by a pair of intersecting slots and each of the intersections being defined by four pegs/pins at the outlet face of the primary extrusion die body. Each of the insert members is adapted to fit into one of the intersections of the die body, where the size and shape of the insert members and the positioning of the insert members into a plurality of the intersections cuts off the flow path of an extrudable material through the plurality of the intersections. Thereby, when a cellular honeycomb structure is extruded through the composite extrusion die, the honeycomb structure comprises a plurality of finned protrusions extending from a plurality of the cell walls of the honeycomb structure corresponding to the plurality of the intersections of the die body into which the insert members are secured.

    摘要: An extrusion die for extruding a honeycombshaped structure having rectangular channels. The die is formed of a hard, rigid material, preferably metal, and includes a body plate and an abutting face plate. The outlet face of the body plate is brazed to the inlet face of the face plate. The body plate has a plurality of slightly staggered primary feed holes, the outlet ends of each communicating with an associated feed reservoir, the latter each defined by a recess or depression in the inlet surface of the face plate. Each feed reservoir communicates with the inlet ends of three associated secondary feed holes. The outlet surface of the face plate integrally carries a plurality of intersecting slot segments defining rectangular pins. The outlet end of each secondary feed hole communicates with and feeds an associated intersection of groove segments. The arrangement is such that the number of slot intersections is greater than the number of secondary feed holes, with two diagonally opposite corners of any pin communicating with a secondary feed hole. The combination of rectangular pins (discharge slots) and staggering of the main feed holes maximizes the die interface brazing area to thereby realize honeycomb cell densities of 900-1400 cells per square inch.

    摘要: Disclosed is an improved ceramic heat recovery wheel driven on a shaft containing a metal hub which may be driven without slippage between the wheel and the hub. The wheel includes a splined metal shaft which mates with the disk including a plurality of radially extending keys equi-angularly spaced about its circumference. The ceramic disk includes an equal plurality of radially extending keyways which mate with the keys. In one embodiment, the keys are situated on only one side of the bore of the ceramic disk and the keyways do not extend through the bore. On the opposite face of the disk, a retainer plate surrounds the shaft. An axial force is applied to the retainer plate for restraining movement of the wheel in the axial direction.

    摘要: Secondary discharge slots are cut into the face of newly made or used extrusion dies such that the secondary discharge slots communicate transversely and longitudinally with primary discharge slots but do not communicate with the feed holes. The novel extrusion die arrangement is set forth for the production of ceramic honeycomb structures which produce a greater number of cells per square inch, protrusions on the cell walls, or a combination of both dependent upon the Primary Slots' Volume to Secondary Slots' volume ratio. The secondary discharge slots can produce honeycomb substrates with much greater surface areas, using an extrusion die with a significantly reduced number of feed holes and a greater number of discharge slots.
